It's about balance and centeredness
Sometimes when people try to "sit up straight", they fix the wrong thing so to speak. I have a picture of myself in college carrying a bass drum, and I can see looking at it how I was trying to correct my posture up high when the problem was down low. No wonder my balance has always been so poor.Also posture is a cumulative thing which affects your muscles and eventually your bone structure. If you consciously sit up straight when playing music but spend the rest of the day slouching, I'm not sure that's going to work out. Kids don't seem to get sore no matter what so they can get away with all sorts of things, but it catches up to you when you get older.
See this article: Posture for Instantly Improved Sound. It talks about the bench and your body and gives you little tips for finding the best position for yourself quickly.
I found this troubling, to put it mildly:"For example, in the introduction for Beethoven’s Pathétique (1st Movement), the dramatic C minor chords are just a drop of the arms, with stiff wrists after the drop, so the sound does not fade, to emphasize the drama."
I don't see what you're getting at-- it's telling people that there are exceptions to the stiff wrist rule. I am a performer and I can vouch for that phrase. You can't use the pedal to hold the notes or else they'll blur-- you'll have to keep your wrists stiff for clear sound.You can send a post in too and they'll publish it if they like it. It's a large, long-term project in the early stages and I know a few very talented individuals involved.
Firstly, there are very few pianists who use a "drop" for that chord. It tends to produce a rather harsh and banged sound, compared to starting from contact. Why on earth could you not use the pedal to hold a single sustained chord without blurring? I'm bemused. And how on earth would the wrists being "stiff" have any effect on a pedalling issue?
Also, what on earth is this supposed to mean?"Adjust your bench until it is comfortable, as long as your body is one armlength away from the piano."What is an armlength? Presumably not a fully outstretched arm- which means that this tells us literally nothing about how the arm is actually supposed to be aligned (except that you are supposed to be able to reach the keys- what an insight!). This is also utter nonsense:"When you’re sitting on the bench, your feet should touch the ground. If not, place a stool or phonebook under your feet so that your legs form a 90 degree angle with the ground. If you have a keyboard (without a bench) find a chair that’s the right height for you."For those with long arms it could mean being totally cramped up against the piano. The exact angle of the legs will vary considerably based on individual proportions. If used as the point of judgement, it could greatly conflict with the ease of aligning the arm. This article is utter bilge. In fact, forget long arms. The only way to play with a 90 degree angle is to never to use the pedal, or sit so close that the knee is directly above it. Sorry to be blunt, but this is total crap. For a young child, it will be necessary to sit relatively close for the arms to reach the keys , which might happen to produce something close to a 90 degree angle. However, no grown adult who uses a pedal can ever produce such an angle without limiting the movement of their arms. Why would this exact angle be a goal? It's pure coincidence that some postures might happen to lead to it. Having the feet at least slightly forward of the knees is a necessity for virtually everyone- and also spreads the weight far more comfortably.Also, in spite of being pointlessly specific and restrictive about the angle between the legs and the ground you didn't define any means of determining the "right height". If this is supposed to help people (rather than mislead them) it needs a great deal more thought put into it.
The things in the Gsmile's link are things that we still see commonly taught - they were taught a lot maybe 10 or more years ago and then before. More and more there are people coming out who are pointing out the damage that has happened from some of this, and giving different approaches that help with sitting & moving at the piano, and also to fix that damage."Sit up straight" already causes a problem. One person wrote "Poor posture is bad. But 'good posture' gotten in the wrong way is much worse." We do awful and unnatural things to ourselves when we try to sit up straight. We lock ourselves into place, we tire ourselves using the wrong muscles. To learn balanced sitting that allows us to move naturally is different. I'd think that getting an observant teacher (not a rigid one with rigid rules) is very helpful."Shoulders back" is really dastardly! It's supposed to help with slouching, without getting at the cause of slouching or what slouching is. Our "shoulders" are part of our arm movement. I'm in the middle of undoing the mess from that advice."Head back" - I assume to stop the "head forward posture" - very easy to then get a "back oriented posture". The head is the top end of the spine which wants to be able to move subtly and fluidly. If you keep your head fixed, nothing else can move easily either.
"It tells you that you stretch out your fist and touch it against the piano."When your arm is entirely outstretched (ie straight from shoulder to hand), you should only just be able to touch the piano? Or when your arm is still bent? I have no idea what you are trying to convey. If it's the former, that leaves me reaching far too much to get between the black keys. I have never seen a pianist in my life, who would be at full reach. If it's the latter, it conveys nothing even faintly specific. There is a massive range of positions where I can touch the piano with my fist. It's as good saying "make sure you can reach the keys"."How can you be cramped when you have long arms? And what are you talking about? I think the 90 degree angle thing is a guideline-- and it tells beginners not to cross their legs?"So why not say "don't cross your legs"- rather than give them a nonsensically precise figure about a position that almost nobody would ever use? If my legs were at 90 degrees to the floor my knee would be straight above the pedals and my arms would be cramped. I'd have to force the stool in all the way. So why specify this? Why even put the idea in a person's head? Even though you don't specify that this is desirable for those who can reach the floor, anyone could easily take it as suggesting it to be a desirable posture. However, it is not desirable in any way. The weight is balanced far better if the feet are forward of the knee- and just about any pianist will need such a position to be able to pedal.
Make a fist in one hand and stretch it out in front of you until it touches the board directly above the keys (or where the board would be, for a electric piano).Make sure your back is straight and your shoulders are relaxed. Have control, not tension.Adjust your bench until it is comfortable, as long as your body is one armlength away from the piano. This trick also makes sure that your feet aren’t too far away from the pedals when you need them.Posture for Instantly Improved Sound
"Making a fist, your knuckles and flats of fingers should be able to touch the piano." Obviously, you don't play this way-- you find your distance, then you take your arm down."? That doesn't tell me anything. I do can this from a whole range of stool positions- many of which are totally unsuitable for playing. In particular, if my arm were fully outstretched, I would be making a very big effort to get between the black keys. As I asked in my last post- is the arm supposed to be fully outstretched or slightly bent? You didn't make it clear. "It doesn't say "don't cross your legs" probably because there are lots of other ways that students place their feet (that I've seen, e.g. on the bench, straight out, one leg bent to the side, etc.) and the most specific and concise way to convey that is at an approx 90 degree angle. When you start there, then your legs would be able to reach the pedals, moving away from the 90 degree angle."Even without pedalling, it spreads the weight poorly if the leg goes straight down. As someone who is tall and sits low, it's essential to have my feet forward of the knees. 90 degrees isn't even terribly good as a point of departure.
"Arm straight right in front of you with a fist, the flats of your fingers touching the piano. It tells you your approx distance. How would it be difficult for you?"It's way too far to reach! Horowitz sits a long way from the piano, but not even close to as far as this puts me! I'm sorry, but this is a poor means of judging. It may coincidentally lead to something that works for some, but there's nothing inherently natural or logical about your means of judging. I regularly play between the black keys (sometimes right at the very back) as just about all good pianists do. If I sat as your yardstick suggests, I'd either have to lean my torso a very long way forward, or I'd have to do so with an almost perfectly straight arm. Come to think of it, seeing as it's based upon the arm being perfectly straight at a point which is scarcely beyond the key at all, I struggle to see how this could work for anyone (other than beginners who only use white keys). How many pianists have to fully outstretch their arms to get between black keys? You should not be have to be anywhere near a fully outstretched arm to access the full range of each key. If there are pianists who do play this way, it's a very unusual choice of posture. This seems geared towards playing that is done right at the front of each key. Pianists need equally comfortable access to the backs of the keys. "As someone who is tall and sits low, your knees probably won't be above your hips-- that's also what the 90 degree angle guideline says."? 90 degrees between the calves and floor has no bearing on whether the knees are above or below the hips. That's about the angle of the thigh.
In ballet, yoga, and many other forms of dance, "good posture" is defined as having the head up, the back straight, and the shoulders relaxed. To relax your upper back and shoulders, just roll your shoulders in a circle, stopping when your shoulders are in the downwards position. That's what the article is telling you, without going into it too much. This is web copy and reading on a screen is fatiguing so less is more.
"You arm has to be straight as in right in front of your shoulder to find your distance. Then you take your arm down and play."Okay, that makes more sense. I'd really clarify that the arm is supposed to be a parallel to the floor though in your explanation. This sentence is highly open to misunderstanding:"Make a fist in one hand and stretch it out in front of you until it touches the board directly above the keys (or where the board would be, for a electric piano).""Directly above the keys" strongly suggests a very small distance above the keys. Also, (while I have an upright myself) this would also be in thin air on a grand piano. The fact you didn't mention that and the phrase "directly" above is extremely open to misunderstanding."There would be too much pressure on your knees if they were above your hips, so there really is no "sitting low" unless your knees are above your hips."There are some people who sit this way- although I certainly wouldn't recommend it personally. I seem to recall that Rachmaninoff had to sit this way.
You will find a growing number of professionals in the fields of yoga, various musical instruments, sports and fitness, and even simple posture and rehabilitation experts - they are all saying roughly the same thing. What was taught in regards to posture ended up creating problems, and it is in those precise areas. They are busy undoing the damage and reteaching it. There is a lot more to it. I am familiar with those principles.
Yes, but how posture was taught has caused problems. I am talking specifically about the main principles that were taught until recently and still are .... not about things specific to things like ballet. In my earlier post I referred to a few resources. Please do feel free to explore them, especially the first - it does make a difference.
A lot of help can come through Alexander Technique.
Beware those less informed Alexander practitioners who say the head balances on the top of the spine. It can't, it's front heavy. There's a big difference between the experience of good posture and the actual physiology.
To say that something is "balanced" does not by implication suggest that the muscles are free to become literally inert.
But it does imply they do less work. The muscles keeping the head in place are always quite active in an erect posture as they have to counteract the frontal weight of the head . Call that balanced if you like, I don't.
The arrangement of head on neck is more of a pulley viz:Now if you want to call that balancing fine, but who then is the pedantic one?
if you think the head on the neck is "more of a pulley" you are simply illustrating the extent of your ignorance. It is not in ANY sense a pulley and neither does it behave remotely like one.
In Your Humble Opinion! We'll just have to agree to disagree.
You obviously have nothing better to do. I do!
Nothing better to do than verify my facts?
I must have missed that verification! Do you wanna run that by me again?
